Which of the following ours filtration at the aeriolar end of the capillary bed.

A
Decrease in hydrostatic pressure of capillaries
B
Increase in hydrostatic pressure of capillaries
C
Increase in oncotic pressure of capillaries
D
Decrease in oncotic pressure of interstitium
High-Yield Explanation
The rate of filtration at any point depend on 1)Hydrostatic pressure gradient(Hydrostatic pressure of capillaries-hydrostatic pressure of interstitium) 2)Osmotic pressure gradient Net filtration pressure = Hydrostatic pr.gradient-Osmotic pr.gradient So increase in hydrostatic pressure of capillaries ours filtration at the aeriolar end of the capillary bed.
